When flush handle is depressed, flapper valve opens and toilet begins flush. As soon as the flush handle is released, flapper closes, resulting in a "no flush" condition. Flush handle must be held down for complete flush. Replaced flapper valve with universal part from hardware store which did not fix the problem. This toilet has a plastic tank inside the porcelain tank, and I'm not familiar with this design. Please help.
Fill the breather hole (1/8" hole) inside the flapper.This is designed to let air out so the flapper will sink. Now it floats longer letting in more water. 25%percent more in my case.
What do you mean by "Fill the hole?" With what?
After 2 plumbers told me I needed to replace the toilet, this led to my "quick fix" that solved the problem. I had planned to use flex seal tape to reduce the hole size until I say the other answer.
Joseph Weisenberger's answer a few down on the list told me exactly what I needed to do. I couldn't find the Kolby flapper he mentioned but the one that was recently installed has an adjustable air hole that I could reduce. One of the plumbers who was by to fix it was actually the guy who recently installed the new flapper (disappointed he didn't know how this works).

Made a video on how I fixed mine.
Try shortening the chain from the flush handle to the flapper. If it's too long, the suction can pull the flapper back before the toilet flushes.

You will need to adjust the chain. They are just clipped at any point when coming from the factory not at the opyimal length. It will take a little effort to find the desired length as sometimes the trick to getting the valve to remain open longer is opposite of what one would expect. I mean there is a point to where there will be more slack in the line than you might expect to get the valve to stay open for the optimal duration.
Hope this helps you.
SOURCE: toto toilet, flapper doesn't stay up long enough to flush
One of two things is the problem. First, make sure that you have a tight chain with little slack. If there's too much slack, the flapper won't catch in the passing air to stay up. Second, the flapper is not correct for that style of toilet. You might want to look into purchasing a new Kolby filter that has a removeable cone in the center. Move that cone to 12 o'clock to allow the maximum amount of water to run through the flush valve. If the flapper you have now is flat, it needs to have a cone in the center on the underside.
SOURCE: Toto Dartmouth toilet flapper/chain design flaw
Your right this is a poor design. Space was the main reason for this and functionality was sacrificed. However, you can get a replacement rod at a major plumbing store. You could rig it by attaching a stem to the valve assembly. Allow the chain or rubber piece to slide over it. It is kind of like putting a permanent finger in the path of the chain to give it a "direct" lift up. This would then force the chain to go up instead of at an angle.

I have minute amount of leakage into the bowl causing mold to grow. I believe that it may be the rubber seal for the flapper body to the porcelain.
SOURCE: Flush valve closes before toilet flushes completely?
lift off cover and adjust =shorten length= between flapper and handle lever
